The world is increasingly become a unified whole in which ideas and people move readily in order to share their ideas and expertise. Many nations fear globalization will somehow reduce the power of their own culture, particularly their language. The Danish government wants to insist that Danish remains the main language of instruction at both the undergraduate and graduate levels. They are very upset at Roskilde University and the Technical University of Denmark where students are taught in the English language. The government wants such un-Danish behavior to cease and everyone go back to using Danish. The concept of teaching in English is to broaden the range of minds made available to students. There are scholars who only know the English language and a high percent of scholarly journals are in English.
The idea of a university is that it brings together the best minds of the world in order to provide students new insights into the areas they study.
